Why dog waste is a bigger health issue in Arizona's heat than people think — parasites, flies, odor, and what weekly cleanup actually prevents in Chandler yards.
1. Parasites don't 'dry up and disappear'
People assume desert heat sterilizes dog waste. It doesn't — roundworm and hookworm eggs survive in soil and gravel for months and can reinfect pets and kids playing in the yard.
2. Heat makes odor and flies explode
At 110°+, decomposition and fly activity spike. A yard that's fine in January is a problem in July with the same amount of waste.
3. Monsoon spreads it
Heavy monsoon rain washes waste and its bacteria across the yard and toward storm drains — a known contributor to local water-quality issues.
4. Weekly removal breaks the cycle
Consistent weekly pickup is the single most effective thing you can do — it never builds up enough to become a parasite, odor, or fly problem.
